I would recommend WEKA- I use it all the time for my Machine Learning work. Octave as ZSayeed mentioned is also good. I would also recommend you look into R - a GNU open source programming language for statistical computing and graphics. There are quite a few R GUIs and IDEs available.

Okay. Thanks everyone. I wasn't looking for software, rather techniques. I'm going with the paired sample test, regression analysis and this thing called ANOVA which I'm still yet to figure out. But thanks anyway, it's the thought and effort that counts and should always count.

And idumb, caffeine intake was a prerequisite for this study. In any case, 4.5 hours is shocking! You really need some big azz shrimps, so the blood goes in your stomach for digestion, making you lightheaded and sleepy.

BC SQUAD UP! And I'm out.
